Weighted means and percentages were computed for continuous and categorical correlates of 12-month and lifetime cannabis use disorder, overall and by severity level. Odds ratios (ORs) from multivariable logistic regressions indicated associations between cannabis use disorder and each sociodemographic characteristic, adjusted for all others. ORs of cannabis use disorders with psychiatric comorbidity were derived similarly. The relationship of 12-month cannabis use disorder to SF-12v2 scales was assessed using linear regression, controlling for sociodemographic characteristics. To account for the NESARC-III complex sample design, analyses utilized SUDAAN, version 11.0 (49).
